Answer:
Yes. If it has one variable and not exponential the solution is 1.
If is one variable and to power of 2 it is quadratic and two solutions.
If it two variable with no power it is simultaneous and with 2 solutions. E.t.c

Step-by-step explanation:
The given area of the shape of 57.8·π cm², and length of the slant sides
being a factor of the radius, gives the length of the radius as <u>3.4 cm</u>.
<h3>How can the length of the radius be calculated?</h3>
Given;
Radius of the two cones are equal.
Slant height of one cone = 2 × Radius
Slant height of the other cone = 3 × Radius
Surface area of the shape = 57.8·π cm²
The curved surface area of a cone = π·r·l
Required:
The radius of the cone.
Solution;
Surface areas of the cones are therefore;
π·r × 2·r, and π·r × 3·r
The total surface area is therefore;
π·r × 2·r + π·r × 3·r = 57.8·π
5·r²·π = 57.8·π
Which gives;
r² = 57.8 ÷ 5 = 11.56
r = √(11.56) = 3.4
- The radius of the cones, r =<u> 3.4 cm</u>

12 and 23
- Two numbers are relatively prime only when they have 1 as the common factor . or in other words they can not be divided by any other number other than 1 and itself.
- To find
- relative prime
- of two numbers we need to find the HCF of the numbers. If the HCF is 1, then the two numbers are said to be relatively primes or in other words only 1 should be common as factor.
- factor of 23 = 2, 2, 3, 1
here only 1 is a common factor.
